*1abrasion-resistant work-hardenable non-magnetizable impact-resistant stainless edge-holding (high-speed steel) creep-resistant (high-speed steel) heat-resistant (temp. > 600 C) *1The wear properties of the weld metal depend on a work-hardening after-treatment. It can be achieved by subsequent hammering or pressing, but also without such after-treatment if the weld metal is exposed to compressive stress, rolling or impact stress during operation
